Worked Solution & Example Answer:A large outbreak of cholera occurred in London in 1894 - Edexcel - GCSE Biology - Question 4 - 2017 - Paper 1
Step 1
Calculate the total number of deaths from cholera in London in 1894.
Answer
To find the total number of deaths from cholera in London, we sum the total number of deaths from cholera in each area:
Total deaths = Deaths in Southwark + Deaths in Lambeth + Deaths in the rest of London
Total deaths = 1,263 + 98 + 1,422 = 2,783.
Step 2
Suggest a reason for the differences in the total number of deaths from cholera in Southwark and Lambeth.
Answer
One reason for the differences in the total number of deaths from cholera in Southwark and Lambeth could be that there were more houses or people in Southwark, leading to higher overcrowding, which can facilitate the spread of disease. Alternatively, cleaner water supply and better sanitation in Lambeth could have contributed to its lower death rate.
